4.1 Therapeutic indications
Ketorolac is indicated for the prophylaxis and reduction of inflammation and associated symptoms following ocular surgery.

Ketorolac is indicated in adults.

4.2  Posology and method of administration
Post-operative inflammation:

One drop instilled into the eye three times daily starting 24 hours pre-operatively and continuing for up to three weeks post-operatively.

Paediatric population
There is no relevant use of Ketorolac in the paediatric population in the indication: For the prophylaxis and reduction of inflammation following cataract surgery.

Method of administration
Ocular use.

Instil one drop of the solution into the inferior conjunctival sac of the eye to be treated, while pulling the lower eyelid gently downwards and looking upwards.

If Ketorolac is used concomitantly with other topical eye medications there must be an interval of at least 5 minutes between the two medications.

4.3 Contraindications
Hypersensitivity to the active substance(s) or to any of the excipients listed in section 6.1.

The potential exists for cross-sensitivity to acetylsalicylic acid and other non-steroidal anti-inflammatory drugs. Ketorolac is contraindicated in individuals who have previously exhibited sensitivities to these drugs.

4.4 Special Warnings and precautions for use
It is recommended that Ketorolac be used with caution in patients with known bleeding tendencies or who are receiving other medications which may prolong bleeding time.

In common with other anti-inflammatory drugs, Ketorolac may mask the usual signs of infection.

All non-steroidal anti-inflammatory drugs (NSAIDs) may slow down or delay wound healing. Concomitant use of NSAIDs and topical steroids can increase the potential for healing problems.

Concomitant use of Ketorolac and topical corticosteroids should be exercised with caution in patients susceptible to corneal epithelial breakdown.

Use of topical NSAIDS may result in keratitis. In some patients, continued use of topical NSAIDs may result in epithelial breakdown, corneal thinning, corneal erosion, corneal ulceration or corneal perforation. These events may be sight threatening. Patients with evidence of corneal epithelial breakdown should immediately discontinue use of topical NSAIDs and should be closely monitored for corneal health.

Topical NSAIDs should be used with caution in patients with complicated ocular surgeries, corneal denervation, corneal epithelial defects, diabetes mellitus, ocular surface diseases (e.g. dry eye syndrome), rheumatoid arthritis, or repeat ocular surgeries within a short period of time, as they may be at increased risk for corneal adverse events which may become sight threatening.

Post marketing experience with topical NSAIDs also suggest that use more than 24 hours prior to surgery or use beyond 14 days post surgery may increase patient risk for the occurrence and severity of corneal adverse events.

The preservative in Ketorolac, benzalkonium chloride, may cause eye irritation. Contact lenses must be removed prior to application, with at least a 15-minute wait before reinsertion. Benzalkonium chloride is known to discolour soft contact lenses. Contact with soft contact lenses must be avoided.

There have been post-marketing reports of bronchospasm or exacerbation of asthma in patients, who have either a known hypersensitivity to aspirin/non-steroidal anti-inflammatory drugs or a past medical history of asthma associated with the use of Ketorolac, which may be contributory. Caution is recommended in the use of Ketorolac in these individuals (see section 4.8).

Patients should be instructed to avoid allowing the tip of the dispensing container to contact the eye or surrounding structures to avoid injury and contamination of eye drops.

Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms.

4.5 Interaction with other medicinal products and other forms of interaction
No interaction studies have been performed.

Ketorolac has been safely administered with systemic and ophthalmic medications such as antibiotics, sedatives, beta blockers, carbonic anhydrase inhibitors, miotics, mydriatics, local anaesthetics and cycloplegics.

Ketorolac may slow or delay healing. Topical corticosteroids are also known to slow or delay healing. Concomitant use of topical NSAIDs and topical corticosteroids may increase the potential for healing problems (see section 4.4).

4.6 Fertility, Pregnancy and lactation
There are no adequate data from the use of eye drops containing ketorolac in pregnant women. Studies in animals have shown reproductive toxicity. Inhibition of prostaglandin synthesis may negatively affect pregnancy and/or embryonal/foetal development and/ or postnatal development. Although a very low systemic exposure is expected after the use of ketorolac eye drops, Ketorolac is not recommended during pregnancy.

Ketorolac should not be used during breast-feeding. Ketorolac is excreted in human milk after systemic administration.

There are no adequate data from the use of ketorolac on fertility in humans.

4.7 Effects on ability to drive and use machines
Transient blurring of vision may occur on instillation of eye drops. Do not drive or use hazardous machinery unless vision is clear.

4.8 Undesirable Effects
The most frequent adverse events reported with the use of Ketorolac are transient stinging and burning on instillation.

The frequency of adverse reactions documented during clinical trials of ketorolac and through post-marketing experience is given below and is defined as follows:

Very Common (≥ 1/10);

*Occasional post marketing reports of corneal damage including corneal thinning, corneal erosion, epithelial breakdown and corneal perforation have been received. These occurred mainly in patients using concomitant topical corticosteroids and/or with predisposing co-morbidity (see section 4.4).

**There have been post-marketing reports of bronchospasm or exacerbation of asthma, in patients, who have either a known hypersensitivity to aspirin/non-steroidal anti-inflammatory drugs or a past medical history of asthma, associated with the use of Ketorolac which may be contributory.

None of the typical adverse reactions reported with the systemic non-steroidal anti-inflammatory agents (including ketorolac) have been observed at the doses used in topical ophthalmic therapy.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product.

4.9 Overdose
No case of overdose has been reported. Overdose is unlikely to occur via the recommended method of administration.

If accidentally ingested, drink fluids to dilute.


5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Anti-inflammatory agents, non-steroids

Ketorolac (ketorolac) is a non-steroidal anti-inflammatory agent demonstrating analgesic and anti-inflammatory activity. Ketorolac inhibits the cyclo-oxygenase enzyme essential for biosynthesis of prostaglandins. Ketorolac has been shown to reduce prostaglandin levels in the aqueous humour after topical ophthalmic administration.

Ketorolac given systemically does not cause pupil constriction. Results from clinical studies indicate that Ketorolac has no significant effect on intra-ocular pressure.

 5.2 Pharmacokinetic properties
a) General characteristics


Rabbit aqueous humor bioavailability:
Mean concentration of total radioactivity0.856 µg-equiv./ml @ 0.5 hr
1.607 µg-equiv./ml @ 2 hr
Tmax3.38 hr
Cmax1.905 µg-equiv./ml
AUC (0-8 hr)9.39 µg-equiv. hr/ml
Total AUC13.53 µg-equiv. hr/ml
Half-life3.77 hr
Absolute ocular bioavailability3.7%

After topical ocular doses in the rabbit the half life of total radioactivity in aqueous humor was longer than after intracameral injection. This suggests that topical dosing may lead to a “reservoir” effect in the corneal epithelium and continued flux of drug from the reservoir into the aqueous humor.


After ophthalmic doses were administered to rabbits, peak concentrations of radioactivity were achieved within 1 hour in the ocular tissues and were highest in the cornea (6.06 mcg-eq/ml). At 1 hour, the majority of the radioactivity (0.9% of administered dose) was recovered from the sclera (0.58%) and cornea (0.24%), and smaller amounts were recovered from the aqueous humor (0.026%), vitreous humor (0.023%), retina-choroid (0.018%), iris-ciliary body (0.007%) and lens (0.002%).

Relative to plasma AUC values, the AUC’s in rabbits were higher for cornea (104 fold), sclera (27 fold), iris-ciliary body (5.8 fold), retina-choroid (5.6 fold), aqueous humor (3.3 fold) and approximately one-half in the vitreous humor and lens. After ophthalmic administration, concentrations of drug-related radioactivity were higher in the ocular tissues and lower in plasma compared with those after IV dosing.

Systemic Absorption

After ophthalmic doses in the rabbit, ketorolac was absorbed rapidly into the systemic circulation (Tmax, 15 min). Plasma half-lives after ophthalmic doses (6.6 – 6.9 hr) were longer than those after IV administration (1.1 hr), suggesting that removal of drug from eye into the venous circulation may be rate-limiting. By comparison of drug levels in aqueous humor after intracameral injection vs. plasma levels after IV administration, ketorolac was shown to clear more rapidly from plasma (6 ml/min) than from the anterior chamber (11 mcl/min).

In the cynomolgus monkey, peak plasma levels of ketorolac occurred at 1.1 hr after the ophthalmic dose. The plasma half-life of ketorolac was similar after ophthalmic (1.8 hr) and IV doses (1.6 hr).

The majority of the ophthalmic dose was excreted in urine (66% in rabbit and 75% in monkey) and a small amount in faeces (11% in rabbit and 2% in monkey). The extent of systemic absorption after ophthalmic dosing averaged 73% in the rabbit and 76% in the cynomolgus monkey.


After ophthalmic administration in rabbits, ketorolac represented the major component (more than 90%) of radioactivity in aqueous humor and plasma and the p-hydroxy metabolite accounted for 5% of radioactivity in plasma. Ketorolac was also the major component (96%) of plasma radioactivity after ophthalmic dosing in monkeys.

After ophthalmic dosing in the rabbit, 72%, 17% and 6% of the total radioactivity in urine was comprised of intact ketorolac, p-hydroxy ketorolac and other polar metabolites, respectively. After IV dosing, the relative proportions of total radioactivity in urine averaged 6% as intact ketorolac, 68% as p-hydroxy ketorolac and 22% as polar metabolites.

In the monkey, intact ketorolac and its polar metabolite accounted for 32% and 65% of the total radioactivity in urine, respectively, after ophthalmic dosing, and 50% and 49% of the radioactivity in urine, respectively, after IV dosing. Thus, the metabolism of ketorolac was qualitatively similar after ophthalmic and IV administration in the monkey and rabbit.

b) Characteristics in patients

Ketorolac tromethamine solutions (0.1% or 0.5%) or vehicle were instilled into the eyes of patients approximately 12 hours and 1 hour prior to surgery. Concentrations of ketorolac in aqueous humor sampled at the time of surgery were at the lower limit of detection (40 ng/ml) in 1 patient and below the quantitation limit in 7 patients dosed with 0.1% ketorolac tromethamine. The average aqueous humor level of ketorolac in patients treated with 0.5% ketorolac tromethamine was 95 ng/ml. Concentrations of PGE2 in aqueous humor were 80 pg/ml, 40 pg/ml and 28 pg/ml in patients treated with vehicle, 0.1% ketorolac tromethamine and 0.5% ketorolac tromethamine, respectively.

In the 21-day multiple dose (TID) tolerance study in healthy subjects, only 1 of 13 subjects had a detectable plasma level pre-dose (0.021 μg/ml). In another group of 13 subjects, only 4 subjects showed very low plasma levels of ketorolac (0.011 to 0.023 μg/ml) 15 minutes after the ocular dose.

Thus, higher levels of ketorolac in the aqueous humor and very low or no detectable plasma levels after ophthalmic doses, suggest that the use of ketorolac tromethamine by the ophthalmic route in treatment of ocular disorders results in quite low systemic absorption in patients.

5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential, toxicity to reproduction and development.

Acute, sub-acute and chronic studies of Ketorolac in experimental animals have established the safety of the drug. In addition, octoxinol 40 was separately evaluated for its ocular safety. Ketorolac was found to be non-irritating, it did not demonstrate a local anaesthetic effect, it did not influence the healing of experimental corneal wounds in rabbits, it did not enhance the spread of experimental ocular infections of Candida albicansHerpes simplex virus type one, or Pseudomonas aeruginosa in rabbits, and it did not increase the ocular pressure of normal rabbit eyes.

Ketorolac contains benzalkonium chloride
This medicine contains 0.1 mg benzalkonium chloride in each milliliter which is equivalent to 0.1 mg/ml.

Benzalkonium chloride may be absorbed by soft contact lenses and may change the colour of the contact lenses. You should remove contact lenses before using this medicine and put them back 15 minutes afterwards.

Benzalkonium chloride may also cause eye irritation, especially if you have dry eyes or disorders of the cornea (the clear layer at the front of the eye). If you feel abnormal eye sensation, stinging or pain in the eye after using this medicine, talk to your doctor.

3. How you will be given Ketorolac
Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. The recommended doseis 1 drop into the affected eye(s), 3 times a day, starting 24 hours before surgery and continuing for up to 3 weeks after eye surgery.

Instructions for use

  • You must not use the bottle if the tamper-proof seal on the bottle neck is broken before you first use it. Apply your eye drops in the following way:
  1. Wash your hands. Tilt your head back and look at the ceiling.
    2. Gently pull the lower eyelid down until there is a small pocket.
    3. Turn the bottle upside down and squeeze it to release one drop into each eye that needs treatment.
    4. Let go of the lower lid, and close your eye for 30 seconds.

If a drop misses your eye, try again.

To avoid contamination or injury, do not let the tip of the dropper touch your eye or anything else.

Replace and tighten the cap straight after use.

Wipe off any excess liquid from your cheek with a clean tissue.

The proper application of your eye drops is very important. If you have any questions ask your doctor or pharmacist.

If you use more Ketorolac than you should
The application of too many drops is unlikely to lead to unwanted side effects. Apply your next dose at the normal time. If, by accident, anyone drinks this medicine, drink fluids to dilute and contact your doctor.

If you forget to use Ketorolac
If you forget a dose apply it as soon as you remember, unless it is almost time for your next dose, in which case you should miss out the forgotten dose. Then take your next dose as usual and continue with your normal routine.

Do not take a double dose to make up for a forgotten dose.

If you stop using Ketorolac
Ketorolac should be used as advised by your doctor. If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible Side Effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.

Side effects related to the cornea (the surface of the eye) may be more likely if Ketorolac is used for longer than two weeks or if you are using topical steroid drops at the same time or if you have a related eye condition. You should see your doctor immediately if you experience pain, increased irritation in the eye or changes in vision.
